Shopify Liquid extension for VSCode is not working

I am using Shopify CLI 2.2.2 and the Theme Check 1.2.0

I have installed the VSCode extension (by Shopify), called Shopify Liquid

However, the plugin in VSCode is not working properly. When the VSCode restarts or opens for the first time, it renders the code properly, but then it does not do anything; it does not render the changes in real-time to find the issues.

In the extension description, it says “syntax highlighting” and “real-time rendering”, so why is it not working? Anyone from Shopify has any thoughts?
